DESCRIPTION OF THE EMBODIMENTS
[0038] Reference will now be made in detail to the present
preferred embodiments of the invention, examples of which are
illustrated in the accompanying drawings. Wherever possible, the
same reference numbers are used in the drawings and the description
to refer to the same or like parts.
[0039] FIG. 1 is a schematic view of an electrical connector
assembly according to an embodiment of the invention. FIG. 2 is a
schematic view for assembling the electrical connector assembly of
FIG. 1. Referring to FIG. 1 and FIG. 2 together, in this
embodiment, an electrical connector assembly 10 includes a plug
electrical connector 200 and a receptacle electrical connector 100.
The plug electrical connector 200 includes a first structural
member A1 and a plurality of first terminals 230, and the first
terminals 230 are disposed in the first structural member A1. The
receptacle electrical connector 100 includes a second structural
member A2 and a plurality of second terminals 130, and the second
terminals 130 are disposed in the second structural member A2.
Here, the first terminals 230 may be inserted to the second
terminals 130 to achieve electrical connection via one-step
assembly process of mutually assembling the first structural member
A1 and the second structural member A2.
[0040] More specifically, the first terminals 230 and the second
terminals 130 of this embodiment are compliant with a specification
of a SMB RF connector of Fachkreis Automobiltechnik (FAKRA). In
other words, each of the plug electrical connector 200 and the
receptacle electrical connector 100 is the FAKRA SMB connector. A
number of the first terminals 230 and a number of the second
terminals 130 are respectively M, and a number of types of the
first terminals 230 and a number of types of the second terminals
130 are respectively N, where 1.ltoreq.N.ltoreq.M and each of N and
M is a positive integer. For instance, six different first
terminals 230 (or second terminals 130) are used to form an
integrated structure (M=6) in this embodiment. These six first
terminals 230 (or the second terminals 130) may be terminals
belonging to one single specification (N=1) or may be terminals
having types different from one another (N=6). Here, the number and
the number of types of the terminals are not particularly limited,
i.e., those who meet the above conditions can all be applied to
this embodiment.
[0041] As described above, FAKRA standard is to provide a connector
system that utilizes key and color codes. Therefore, there are
various connectors with specifications (colors) of different types.
Consequently, such diversification would lead to inconvenience and
burden on production, management, and assembly.
[0042] Accordingly, this embodiments of the invention provide an
integrated terminal set by selecting required terminals and
performing a modularization on them. In this way, the electrical
connection may be completed for the terminals with various
specifications simply via one-step docking process. At the same
time, with a single structure produced from said modularization,
not only can costs be reduced since the manufacturing process in
terms of molds, materials, etc., can be simplified, the management
burden may also be substantially reduced by the simplified
manufacturing process.
[0043] FIG. 3 is an explosion view of a receptacle electrical
connector. Referring to FIG. 2 and FIG. 3 together, in this
embodiment, the second structural member A2 of the receptacle
electrical connector 100 includes a second body 110, a first
shielding shell 140 and second shielding shells 120. The second
body 110 includes a second base 112 and a plurality of second
protrusions 114 extended from the second base 112. The second body
110 has a plurality of second inserting holes 112b, penetrating the
second base 112 and the second protrusions 114. The second
terminals 130 are inserted to the second inserting holes 112b and
substantially located in the second base 112 and the second
protrusions 114. The first shielding shell 140 is disposed and
surrounding the second body 110. The second shielding shells 120
are respectively assembled to the second body 110 such that any
adjacent two of the second terminals 130 are spaced apart by the
second shielding shell 120.
[0044] More specifically, the second body 110 has a positioning
protrusion 116 and a locking groove 112c, and the first shielding
shell 140 has a positioning groove 146 and a locking protrusion
142. The first shielding shell 140 is composed of, for example,
four side walls W1, W2, W3 and W4 connected in from of ring. The
positioning groove 146 is located on the side walls W3 and W4, and
the locking protrusion 142 is located on the side walls W1 and W2.
Therefore, the second body 110 and the first shielding shell 140
are positioned together by the positioning protrusion 116 and the
positioning groove 146, and the second body 110 and the first
shielding shell 140 are held together by the locking groove 112c
and the locking protrusion 142. Furthermore, as shown in FIG. 3,
each of the second shielding shells 120 is disposed and surrounding
the corresponding second protrusion 114. More specifically, the
second shielding shell 120 has a sleeve 122 and a pair of pins 124.
The sleeves 122 are sleeved on the second protrusions 114, and the
pins are extended from the sleeve 122 and inserted to third
inserting holes 112a on the second base 112 so the second shielding
shell 120 can be successfully secured on the second body 110.
Accordingly, the receptacle electrical connector 100 is able to
maintain favorable electromagnetic shielding effect with peripheral
electronic components through the first shielding shell 140 so the
receptacle electrical connector 100 and peripheral electronic
components can operate independently without producing mutual
electromagnetic interference. At the same time, with the presence
of the second shielding shell 120, the electromagnetic shielding
effect may be kept between the second terminals 130 so each of the
second terminals 130 can transmit data without suffering mutual
electromagnetic interference.
[0045] FIG. 4 is an explosion view of a plug electrical connector.
With reference to FIG. 4, the first structural member A1 includes a
first body 240 and a front cover 220. The first body 240 has a
plurality of first inserting holes 241. The first terminals 230 are
inserted to the first inserting holes 241, and the front cover 220
covers a part of the first body 240. More specifically, the first
body 240 includes a first base 242, a side wall 244 and a plurality
of first protrusions 246. The side wall 244 and the first
protrusions 246 are extended from the first base 242 in a same
direction, and the side wall 244 surrounds the first protrusion
246. Each of the first inserting holes 241 penetrates the first
base 242 and each of the first protrusions 246, and the front cover
220 covers the first base 242 such that the side wall 244 and the
first protrusions 244 pass through the front cover 220.
Furthermore, the electrical connector assembly 10 further includes
a circuit board 210, which is overlaid by the front cover 220 such
that the part of the first body 240 is located therein, and the
first terminals 230 are respectively inserted and electrically
connected to pads 212 of the circuit board 210.
[0046] Referring back to FIG. 2, in this embodiment, the first
terminals 230 are modularized into the plug electrical connector
200, and the second terminals 130 are modularized into the
receptacle electrical connector 100. In this way, rather than
connecting the first terminals 230 and the second terminals 130 one
by one, the user may have the first terminals 230 and the second
terminals 130 correspondingly and electrically connected to one
another simply by performing the one-time docking action on the
first structural member A1 and the second structural member A2.
Moreover, in the first structural member A1, the first body 240 has
an engaging recess 248; and in the second structural member A2, the
first shielding shell 140 has an engaging point 144. Accordingly,
the plug electrical connector 200 and the receptacle electrical
connector 100 may be connected together securely through the mutual
cooperation of the engaging recess 248 and the engaging point
144.
[0047] FIG. 5 is a schematic view of an electrical connector
assembly according to another embodiment of the invention. FIG. 6
and FIG. 7 are schematic views for assembling the electrical
connector assembly of FIG. 5. Referring to FIG. 5 to FIG. 7, in

[0048] FIG. 8 is an explosion view of a receptacle electrical
connector. Referring to FIG. 7 and FIG. 8 together, in this
embodiment, the second structural member 310 of the receptacle
electrical connector 300 includes a second body A4, and the second
body A4 is further divided into the second base 311 and a second
side wall 315. The second side wall 315 is extended from the second
base 311; the second base 311 has a plurality of second inserting
hole 312 for the second terminals 320 being accommodated therein;
and parts of the second terminals 320 passed outside the second
base 311 are surrounded by the second side wall 315, as shown in
FIG. 7.
[0049] FIG. 9 is an explosion view of a plug electrical connector.
Referring to FIG. 6, FIG. 7 and FIG. 9 together, in this
embodiment, the first structural member A3 includes a first body
430 and a front cover 440, and the first body 430 has a plurality
of first inserting holes 436 for respectively inserting the first
terminals 420 to the first inserting holes 436. The front cover 440
is used to cover a part of the first body 430. More specifically,
the first body 430 has a first base 432 and a first side wall 434;
the first side wall 434 is extended from the first base 432; the
first base 432 has the first inserting holes 436 described above;
and a part of each of the first terminals 420 passes through the
first inserting hole 436 and is surrounded by the first side wall
434, as shown in FIG. 6 or FIG. 7. Furthermore, the electrical
connector assembly 20 further includes a circuit board 410, which
is overlaid by the front cover 440 such that the part of the first
body 430 is located therein, and the first terminals 420 are
respectively inserted and electrically connected to pads 411 of the
circuit board 410.
[0050] FIG. 10 is a cross-sectional view of the electrical
connector assembly of FIG. 5. Referring to FIG. 6, FIG. 7 and FIG.
10, in this embodiment, the first body 430 has a guiding groove 438
and a bump 431, which are respectively used to engage with a
guiding rib 313 and a clamping piece 314 of the second structural
member 310 to position and hold the first body 430 and the second
structural member 310 together.
[0051] More specifically, the second structural member 310 has the
guiding rib 313 located on the second side wall 315, which may be
guided by and engaged with the guiding groove 438 on the first side
wall 434 to provide a positioning effect in the process of
inserting the second body A4 to the first structural member A3. At
the same time, the second structural member 310 further includes
the clamping piece 314, which is disposed on the second base 311
and extended and suspended on the second side wall 315, as shown in
FIG. 7 and FIG. 10. The clamping piece 314 includes a supporting
point 314a, a pressing part 314c and a clamping part 314b. The
supporting point 314a is connected to the second base 311 of the
second body A4 and located between the pressing part 314c and the
clamping part 314b. In other words, the pressing part 314c and the
clamping part 314b are extended form the supporting point 314a
respectively in opposite directions. The pressing part 314c is
suspended on the second base 311, and the locking 314b is suspended
on the second side wall 315. In this way, the clamping piece 314 is
adapted to engage with the bump 431 of the first structural member
A3 to hold the second body A4 on the first structural member A3.
Conversely, the user may apply force to the pressing part 314c to
release the coupling relationship between the clamping part 314b
and the bump 431, so as to easily detach the plug electrical
connector 400 and the receptacle electrical connector 300 from each
other. In addition, the clamping piece 314 and the bump 431
disposed on one single side of the structural member may also
provide an anti-misinsertion effect when docking with the
connector.
[0052] It should be noted that, referring back to FIG. 10, while
being assembled to the second inserting holes 312, the second
terminals 320 can successfully produce a structural interference
with the second structural member 310 through pushing parts 316 of
the second structural member 310 located in the second inserting
holes 312 to be positioned and secured inside the second structural
member 310.
[0053] In summary, in the foregoing embodiments of the invention,
in order to provide a more efficient manufacturing and usage
conditions for the SMB RF connectors compliant with Fachkreis
Automobiltechnik (FAKRA), the electrical connector assembly of the
invention includes the plug electrical connector and the receptacle
electrical connector, which are respectively formed by modularizing
the first terminals and the second terminals of the required
specification. In other words, to improve the production and
assembly efficiency, the terminals of the required specifications
are integrated together through the structural members in advance,
so as to form the integrated terminal set. In this way, the
electrical connection effect may be completed for the terminals
with various specifications simply through the one-time docking
action. At the same time, with a single structure produced from the
modularization, not only can costs be reduced by simplifying the
manufacturing process in terms of molds, materials, etc., the
management burden may also be substantially reduced by the
simplified manufacturing process.
[0054] It will be apparent to those skilled in the art that various
modifications and variations can be made to the structure of the
present invention without departing from the scope or spirit of the
invention. In view of the foregoing, it is intended that the
present invention cover modifications and variations of this
invention provided they fall within the scope of the following
claims and their equivalents.
